M20-7853246

Overview

The Harwin M20-7853246 is a single-row, through-hole socket header from the M20 series. It features a 2.54 mm pitch and accommodates 32 positions. The connector utilizes nickel-plated tin contacts made of phosphor bronze for reliable signal transmission. Designed for board-to-board applications, it employs a nylon housing rated UL94V-0 for flame resistance. The unit supports a maximum current rating of 12A per contact and operates within a temperature range of -55°C to 105°C.

Feature Summary

• Dual-beam contact design ensures improved electrical connection stability and enhanced mechanical reliability during mating cycles.
• High-density compact housing construction allows for optimized PCB space utilization while maintaining strict height limitations.
• Thermoplastic insulation material provides high thermal stability and compatibility with standard surface mount reflow soldering processes.

Applications

• Embedded PC motherboard interconnections
• Industrial monitoring system control boards
• Communication equipment backplanes

Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm exact pin count and termination style. Ensure compliance with RoHS directives if required by your assembly specifications. Cross-reference the part number with authorized distributors to confirm current availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a robust, high-current through-hole solution is required for dense board-to-board connections. The 12A rating suits power distribution needs, while the 2.54mm pitch aligns with standard industrial interfaces. Consider the operating temperature range and UL94V-0 rating for environmental resilience in demanding electronic assemblies.

Part Context

This component belongs to the Harwin M20 series, a widely adopted standard for industrial and consumer electronics. The series offers various configurations including single and double rows with multiple position options. It serves as a foundational interconnect solution for embedded systems requiring durable and standardized connectivity.

Replacement Considerations

Compatible substitutes include other M20 series headers with matching 2.54mm pitch and 32-position counts. Verify that alternative parts maintain identical through-hole termination and nylon housing specifications to ensure mechanical fit and electrical performance equivalence.
